Dropped screw in engine bay - aaah!

I dropped the screw in the gap between the engine and the fan near the front. Landed somewhere at the bottom. Sounded plastic.

What to do, should I be worried, will it fall out, will it catch anywhere, will i need to remove the bumper, bottom tray to find it??

go to an auto store, and borrow a magnetic fishing tool to search for it. I went to a pep boys, but idk if they have that in UK

I dropped the clip for my headlight bulb down and had to fish it out using a magnetic grasping tool. worked like a charm.

Tap the bottom and listen for it, to get an idea of where to fish for it.

Just went for an hour drive. Is it likely it will fall out on its own?

It was the phillips screw driver bit that fell down

honestly, probably not.

Those plastic trays on the bottom overlap each other pretty well. But at any rate, it *shouldn't* do anything if you decide to leave it.

I have dropped a torx bit in the engine bay and left it for 2 weeks before I got the under tray off and it was still there. I would not worry too much it will still be there

Can you remove the under tray without removing the bumper?

Well one thing is good I guess that it's sealed fairly good from the road underneath?

small stick with ducked tape on so sticky side exposed works a treat.

Probably is that I can't even see where it's at anymore.
Or did you mean from underneath?

Yes, you can remove the undertray without removing the bumper. IIRC there about 15 hex bolts that hold it on and it just slides off
